The engines of the Factory versions differ from the standard ones in the following characteristics:
» Black magnesium cases: a bold design that combines aesthetics and pure performance. The new magnesium cases reduce the weight by about 2 pounds compared to the standard version, giving the bike uncompromising agility and responsiveness. Taking advantage of the new cooling circuit designed for the 2026 Sincro, the coolant does not come into contact with the magnesium alloy, preventing corrosion. This is made possible by a nylon insert mounted inside the engine case – clutch side, which creates a hidden coupling between the water pump outlet and the cylinder inlet.
» Clutch (only for 250-300cc engines): the new diaphragm-style clutch uses a higher number of clutch disks over the standard model (7 instead of 6), while maintaining the same external dimensions. This variant allows for precise control and consistent operation, maintaining the same smoothness at the clutch lever even with excessive use. The new clutch ensures approximately 20% more torque during high RPM use. All this is particularly useful in managing the most extreme repeated actions, even at high rpm. The Sincro Factory clutch can also be adjusted to three different positions by changing preload on the diaphragm spring for each rider’s preference.
» Red anodized engine oil caps. More durable and to give that “Factory” look.
» Titanium exhaust: the entire exhaust system has been redesigned. The titanium exhaust manifold on the 250/300 models reduces weight by over 1.1 lbs. and improves performance at medium-high revs, thanks to the increased internal diameter. The silencer has also been redesigned to work in conjunction with the new manifold, creating a more direct system that enhances maximum power and makes the throttle response more responsive. The result is precise and responsive power delivery, which still maintains the excellent manageability of the engine, thanks to the new layout.
The SINCRO Factory 125 and 200 exhaust, also in titanium, differs from that of the larger displacement models in the first part of the manifold, which has a reduced diameter and length (cylinder side), and in a dedicated terminal. The silencer has been resized with a shorter length and a smaller diameter inner tube (compared to 250-300cc), helping to optimize the performance of these two smaller engines.
In keeping with Beta tradition, the Trial Factory models are equipped with a more powerful engine than the standard model, thanks to the lighter weight of the cases, the new titanium exhaust system, and the dedicated cylinder. The bike is more responsive, while the engine ensures greater performance and rideability, guaranteeing explosive power and performance at a higher level when needed. Handling is exemplary, and vibration is reduced to a minimum.
The new Sincro 300 2-stroke Factory is equipped with a brand-new engine, both in terms of the CYLINDER and the HEAD, which houses two SPARKPLUGS. This system has been used on Beta’s off-road Race models with success, and now it arrives on the Factory Sincro for the sport of trial.
The use of a dual sparkplug engine on the 300 2-stroke displacement represents a significant step forward in terms of efficiency and consistent performance. The presence of two ignition points also ensures more uniform combustion within the combustion chamber for the Sincro engine, reducing detonation and improving smoothness at low revs, which is crucial in trials where low speed control is everything. This system ensures faster and more controlled combustion, optimizing engine response and increasing manageability. In addition, the double sparkplug contributes to better engine heat management, reducing the risk of fouling and promoting consistent performance even under prolonged use. The result is a more responsive, smoother, and more powerful bike, capable of tackling technical sections with greater precision and confidence.
The new dedicated cylinder also features a different EXHAUST port design, where the flow is managed differently and more directly than on the standard model, all with the aim of increasing responsiveness and torque at low revs. The cylinder, together with the new double sparkplug engine head and redesigned exhaust system, which contribute to increasing performance at maximum rpm, creates a high-performance engine with a decisive yet manageable character throughout the entire range of use.
To control the new engine, the ECU control unit has also been modified, particularly with regard to the advance map, which has been suitably calibrated to balance the increased performance resulting from the use of the above-mentioned components.
All Sincro Factory models are not equipped with an electric starter motor, which represents an avoidable weight in racing. An electric starter cannot be added to this model due to the special engine cases.
